塞するなど極めて危険な結果を生ずる。When connecting the connection tube of a body fluid circulation circuit or blood pump to the end of a cannula attached to a circulatory system organ, etc.
The connection must be made without leaving any air bubbles in the tube; if air bubbles are included in the blood, this will cause extremely dangerous results such as occluding capillaries.

管端部を接続する。As a method for connecting two tubes filled with blood, etc. without leaving any air bubbles, we used the conventional method of connecting the end of the JY nerve attached to the circulatory system organ and the connecting tube of the blood pump without leaving any air bubbles. To explain using an example, the end of the cannula attached to the organ is oriented upward, blood is raised into the tube by blood pressure, the tube is first clamped below the blood surface, and then the end of the cannula above the clamp part is raised into the tube. Fill the body fluid substitute tube with, for example, physiological saline and shake the tube sufficiently to completely expel any air bubbles remaining on the tube wall.Meanwhile, the connection part of the blood pump connecting tube is also bubble-free. Fill with physiological saline, bring the ends FEE of these two tubes close to each other, and connect the ends of both tubes in the flowing liquid while pouring a large amount of physiological saline into the approach area.

を生じ易く危険である。Even with this method, air is often entrained and drawn into the tube as bubbles. In addition, in many methods of connecting a cannula attached to a circulatory system organ and an extracorporeal circulation circuit, the tube is bent after connection, and the branch part of the side tube provided in the -force tube is connected to the highest point of NrN. A method is used in which the air bubbles are guided by the air bubbles, and then allowed to rise into the side pipe and be removed. However, this method is dangerous because if heparin is not contained in the blood, thrombus is likely to occur at the side tube bifurcation.

の無気泡接続法に在る。The gist of the present invention is to inject blood and/or body fluid substitute fluid into each of the through holes of a connecting container, which has through holes for pipe types at two predetermined locations on the side wall and is provided with a flexible and externally deformable portion. After tightly inserting the tube ends of the two filled tubes, the connecting container (filled with a body fluid substitute liquid, and using the deformability of a predetermined portion of the connecting container under the liquid level) The present invention is a bubble-free connection method for blood, etc.-filled tubes, which is characterized in that both tubes are connected after eliminating air bubbles in each tube.

うしを迎接させることがてきる。The method of the present invention provides a container that has a flexible, elastic and deformable portion (including cases in which the container itself is deformable), and a wall surface (with a connection formed by providing two through-holes for the pipe type). Fig. 1 is a perspective view of an example of such a connection container, and Fig. 2 is a vertical cross-sectional view passing through the center line of the through hole.Connection container 1, length 5c
A transparent, deep-bottom, thin-walled container with a width of about 3 cm and a depth of about 7 cm and a flash thickness of about 1 mm is used, and a through hole 2 for the pipe type with a flange 3 provided on the bottom side of one longitudinal side wall is provided. A skirt 4 is continuously provided on the outside thereof. A flange 3a and a skirt 4a are similarly provided on the opposing wall, and a through hole 2a for all pipe types is provided so that the center line of the through hole 2 substantially coincides with its center. Further, a flange portion 5 is formed on the upper edge. Since this connection container 1 is molded using, for example, a soft vinyl chloride resin, it is transparent, and the container itself is flexible and elastic and can be deformed. That is, it is possible to bend it by gripping it with the palm of your hand, and press the side wall provided with the through holes from both sides to bring the through holes into contact with each other.

透孔２，２ａの径は挿通すべき管を密に嵌着させ、前述
の容器の変形に際しても容器Ｂｆとの密嵌性が確保され
るためには挿通すべき血液充填管の挿入部外径の７０〜
９５％とすることが好ましい。The diameters of the through-holes 2 and 2a are set so that the tube to be inserted therein is tightly fitted, and in order to ensure a tight fit with the container Bf even when the container is deformed as described above, the diameter of the blood-filled tube to be inserted is set so that the blood-filled tube to be inserted is outside the insertion part. Diameter 70~
It is preferable to set it to 95%.

あることが好ましい。The skirt 4 functions as a pulling lug when the tube is inserted into the through hole while pushing through the hole, and is extremely effective when inserting the tube. In addition, the flange portion 5 prevents free deformation of the flexible container, maintains the generally box-shaped container shape, prevents the body fluid substitute from overflowing from the container, and prevents the flange portion from deforming the container due to pressure or the like. Since the deformation of the tube is not large, it is convenient and easy to operate when performing the following steps of filling with a body fluid substitute and later connecting a tube to an adult cow. In addition, all of the parts of this connection container corresponding to the edges and apexes of the box are formed into gently curved surfaces, which prevents air bubbles from remaining inside the container, especially in the above-mentioned parts, when filling with the reeds. There is. The connection container preferably has a transparent wall in order to facilitate checking for residual air bubbles in the container and making it easier to perform pipe connection operations.
